Diet of the blue petrel at sub-Antarctic Marion Island
Food samples were collected from 49 blue petrels Halobaena caerulea at Marion Island in the sub-Antarctic region. These were analysed and the results compared with previously published data collected at other islands. Crustaceans formed the major prey by mass (59,5%) and frequency (100%), with Eupha...

| Summary: | Food samples were collected from 49 blue petrels Halobaena caerulea at Marion Island in the sub-Antarctic region. These were analysed and the results compared with previously published data collected at other islands. Crustaceans formed the major prey by mass (59,5%) and frequency (100%), with Euphausia vallentini being of particular importance (56,6% by mass of Crustacea). Other prey included fish, cephalopods and two species of insects, a moth (Noctuidae) and an assassin bug Nabis. Voedselmonsters van 49 bloustormvofils Halobaena caerulea is by Marioneiland in the sub-Antarktiese gebied versamel. Die voedselmonsters is ontleed en die bevindings met reeds gepubliseerde data wat by ander eilande versamel is, vergelyk. Skulpdiere het die hoofprooi volgens massa (59,5%) en frekwensie (100%), gevorm en Euphausia vallentini was van besondere belang (56,6% van die massa van die skulpdiere). Ander prooi het vis, koppotiges en twee soorte insekte, 'n mot (Noctuidae) en 'n roofinsek van die genus Nabis, ingesluit. |
